This command succeeds and returns 0.

When I change the dependency of ruby-bindings from libnotmuch.so to
libnotmuch.dylib and run `make', I get errors like below.

Looks like mkmf.rb (I have no idea what this is) is provided by OS X by
default, but actually running it fails.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
	--with-opt-dir
	--without-opt-dir
	--with-opt-include
	--without-opt-include=${opt-dir}/include
	--with-opt-lib
	--without-opt-lib=${opt-dir}/lib
	--with-make-prog
	--without-make-prog
	--srcdir=.
	--curdir
	--ruby=/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby

You have to install development tools first.
